Bifacial Rooftop Vertical Solar Panels Shine In Norway - CleanTechnica

The article highlights a pioneering solar installation in Tromsø, Norway—located north of the Arctic Circle—where the world’s largest array of vertically mounted bifacial solar panels has been installed on the roof of Tromsøterminalen, a cold storage facility. Installed by Oslo-based Over Easy Solar, this vertical photovoltaic (VPV) system is designed specifically for northern climates, addressing challenges such as low sun angles, high wind exposure, and heavy snow accumulation that typically hinder traditional flat or angled solar panel installations in such regions. Vertical mounting allows the panels to capture more energy from low-angle sunlight, generate electricity during peak demand times in the morning and afternoon, and avoid snow buildup, thus improving year-round performance and ease of maintenance. Over Easy Solar emphasizes that conventional flat roof solar systems, often developed for southern climates, are vulnerable to wind uplift and snow load, which can damage both the panels and the roof. In contrast, the VPV units feature an aerodynamic, low-profile design that reduces wind exposure and distributes
